Match the humidities with their description. 1. reading with the most water in the air. 2. reading with 80% water in the air. 3. reading that shows the air could hold 80% more water. 4. reading with the lowest amount of water in the air. a. humidity of 20% b. humidity of 80% c. humidity of 90% d. humidity of 10%

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )

The empirical formula of a compound is ch2o and its mass is 120 amu/molecule, what is its formula?

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
